FIELD AND BACKGROUND OF THE INVENTION

[0001] The present application relates to time period setting device of a timer, with which several pre-set time period can be set, the position ON/OFF of circuit is changed in these time period; the present application denotes especially a device for setting “Hour” and “Minute”.

[0002] There are many setting mode of conventional timer in the market, such as mechanical (setting via stirring keyboard is general) and electronic (using key controlling), i.e. there are a variety of timer; basically, mechanical setting is an easier setting, but the divide of each time period is larger, in other words, which can only make a coarse setting time period; and for electronic setting the usable space on the setting disk is not large, because there are many keys therein, the man who not knows the operation well or whose finger is coarse makes easily an erroneous setting, and it's more difficult in operation. The present application is an electronic timer, for smaller numeral change, such as setting ON/OFF, setting switching timing/present time, “week X” etc., which are controlled by the keys, and for two larger numeral change, such as “Hour X ” and “Minute X”, which are set by means of rotating rotary disk mode, the object of correct setting can be easily achieved.

SUMMARY OF THE INVENTION

[0003] The object of the present application is to provide a device for setting the time period; its general condition is as below:

[0004] 1. function: setting time ON/OFF for several groups timing 1-7 days,

[0005] 2. Program mode: divided into displaying present time (clock) and setting time period,

[0006] 3. Explaining the function of keys:

[0007] a. Clock mode-displaying present time mode,

[0008] (a-1) key “ON/OFF”: switching ON/OFF output,

[0009] (a-2) key “Clock +Day”: regulating present week (MO-SU),

[0010] (a-3) key “Clock” +rotary disk rotated clockwise: regulating “Hour” for present time,

[0011] (a-4) key “Clock” +rotary disk rotated counter clockwise: regulating “Minute” for present time,

[0012] (a-5) key “Timer”: entering into program mode,

[0013] *under clock mode, key “Day” and rotary disk are clock wise/counter clockwise rotated, alone use will be without function, the function to be produced must match key “Clock”,

[0014] b. program mode: setting time mode,

[0015] (b-1) key “ON/OFF”: without function,

[0016] (b-2) key “Day”: regulating day (of week) of timer ON/OFF, there are 11 settings for date, such as MO, TU, WE, TH, FR, ST, SU, MO-FR, SA-SU, MO-SA, MO-SU,

[0017] (b-3) rotary disk rotated clockwise: setting time “Hour” of timing function,

[0018] (b-4) rotary disk rotated counter clockwise: setting time “Minute” of timing function,

[0019] (b-5) key “Timer” ON/OFF time setting switching (1 ON→1 OFF→2 ON→ . . . →6 OFF) of 6 groups ON/OFF for timing function,

[0020] (b-6) key “Clock”: returning clock mode,

[0021] c. key “Reset”: all memories are cancelled when the key “Reset” is depressed whether it is under clock or program mode, and the program is again started.

[0022] As above-mentioned, the characteristics of present application is to provide a structure setting “Hour X” and “Minute X”, in which setting Hour/Minute is operated by clockwise or counter clockwise rotation, without the necessity for setting too much keys on a dial, the position such as erroneous trigger etc. produced at the time setting “Hour” and “Minute” of larger numeral change can be avoided. The technical solution of the present application is in that, a rotary disk is provided in the outer edge, a ringed structure having several projecting teeth is driven by rotating the rotary disk, and a sliding structure which can be moved to right/left by stirring the projecting tooth, a contact structure of breaking over circuit is provide on the sliding structure, the Hour/Minute can be quickly set by means of contact (producing pulse) time on the special area of circuit board for the structure.

[0023] The circuit part of timer in present application will be no more described because which belongs to conventional technical, and is not claimed in present application.
